The Schedule referred to :'u these Letters Patent and making part of thesame.

To all whom it may concern Be it known that we, WILLIAM A. FosKETT andHENRY B. TYLER, of New Haven, in the conntyot' N ew Ha\'cn,and State-ofConnecticut, have invented a new andfuseful Machine forliannthcturingBrushes; and we do'hercby declare that the following is a full and exactdescription ot7 the sumo, reference being had to the, accompanyingdranvings, and to the letters of reference marked thereon.

Similar letters of reference, where theyoccur inthe separate views,indicate like parts.

Our invention relates to certain'improvements in the construction ofmachines for manntii'cturing brushes, for which improvements a caveatwas tiled by -ns on the 26th day of December 1S68. v

Ourinvention consists ill-placing the operative parts of the machineinsuch a position, with relation to eachl other, -as to greatly simplifythe whole' machine, rendering it more compact, much less complicated,and, consequently, less liable to get ont ot' order. g

In obtaining this result, we have originated several new modes andcombinations, to be hereafter described. These render the -m`ziichinepractical, which has never before been done, as, inthe machine now inuse, for which a patent-was granted to A. M. White, December 22, 1868,(upon which our invention is an improvemeuh) it has been found that thegreat complicity of paris renders it too expensive, and too liable toget out' oford'er, to be of practical advantage, whereas, in ourmachine, all the parts are of thesinu-)lest possible constrnctiomland weare enabled, by the yuse ot' our iinprovcmenis, to perform the workbetter and iaster than in the other machine We are also able to'produccmany diti'erent variations, both vin size and form, of the brushes,which could not be done upon the origi nal machine. y

The novel portions of our invention are,t-he two corresponding sets ofinclines, in connection wit-l1 the punch, for varying the throw ot thesame; separating the former from its operating-lever, to allow of itsbeing easily rexnoved;the peculiar method of operaiaatingthe divider, inorder that it may be moine eicctual iu its work, and be-in'dependent ot'the vfingers; the slide for elevating orl depressing the table uponwhich the block is held, to allow the use of a block of any thicknessfor a brush-back; the centre-pin, to he used as a guide for the block,while the bristles are being placed therein the arm attached to thetable, in connection with the index, for the purpose of holding thebrush-block ut. an y given angle with the punch; placing the cams which'operate the fingers and slide" upon the main shaft', forf'the purposeof simplifying Atheir operation, and. making the machine more compact;feeding the bristles from Vtherear end ofthe machine,'to facilitate theoperation, and make the machine more compact; the cam or incline, inconnection with a pin, for locking and holding the fingers apart for acertain portion of the receding movement; also, the inode ot' thuslocking the'iingers by any other mechanism, for the purpose of allowingthe other portions ot' the machine to .perform their functions with-Jout inte1i`erence; the camshaped pin in the end of the slide, whichoperates iuconnection withthe lingers, to allow for the' inequalitybetween the two ends ot' the bunch of bristles; and a slide, to operateimmediately the fingers have receded, to hold the bristles in position,and prevent any being drawn backhy the A low the crank-pin or cam-rollerby which the said punch is operated,t\vo steel blocks or'cams, D and E,-both ot' which are provided with corresponding inclines, as shown intig,'4.

'lhe object o i' these incliues' is to provide a means of varyingthe-lengtl1 'of stroke ofthe punch. This is done by. changing the saidblocks, placing-upon the punch a set in which :the angles ot' theinclines are more or less acute, as theV case may require,l in order tolengtheuor short-en the stroke.

In the lower portion'otthe head O, the former F is placed, over whichthe wire is bent by the descending of the jaws ot' the punch. The saidformer slides back and forth in'beairings' formed in the head,'andisoperated by means of a 'lever, G, which, in turn, is operated by acamuponthe main shaft, revolving wit-hin the said head C.

In the original machine, the f'ormerand lever were made of' one and thesame piece. This subjected it to the incon.'enience, that whateverstrain there might be upon thefbrmer, caused by the bending ofthe wire,

. would actually come at the point where the said f'ormer In ourimprovement, however, all these dificulties are done away with, b'ymaking the former and le'vcr entirely separate from each other, as shownin tig. 4. The former is heldin bearings inthe head, which take. all thestrain, and by which it is held more rmly thanA could possibly be donein any other way.

This mode of' construction also provides a means of retempering orreplacing, by a new one, the said former, without disturbing or alteringthe-position of the lever G.

Just backof the head O, upon which it is heldin proper bearin gs, aslide, H, is placed, which is attached to andoperates thedividerby-means of' the cam I, placed upon the. shaft of' the feeding-device.

In the originai machine, this divider was made to `operate with and wasreally a component part of' the fingers, making its operation entirelydependent upon the said fingers, causing great inconvenience inadjustment, and being continually liable to get out of' order. In ourmachine., by placing the divider upon the slide H, as beforcdescrbed, weseparate it entirely from all connection with the fingers, and obtainthe desired resuit with greater certainty, and with less troubleandinconvenience.

Held in semicircular bearings below the head C, we t and hand-wheel b,as shown in fig. 2.

In the centre of` the table J, and projecting a short distance throughit, perpemlicularly, inline with the punch, we place. a centre-pin, L,the object of' which is to actas a guide to the block', in order that,by the use of' a pattern, upon which the brush-back is held, (the lowersurface of' which pattern is `furnished with a number of holes exactlycorresponding'to those in the said brushback,) the said p in L may enterone of the holes in the pattern, andy thus present the correspondinghole in the brush-back in proper position under the punch for'theinsertion of bristles.

The pin L is held in the slide K, and may be raised or lowered, if'necessary, by means of the screw c, to which it is attached, as shown infig. 2.

In making certain kinds of' brushes, particularly those of' oval f'orm,it is necessary to bore the holes, and place the bristles in thebrush-back or block, at different angles with each other, each rowhaving its own particular angle. with reference to thel said block. Toobtain these angles-that is, to hold the block in the propel' position,or at the proper angle,.in order that the holes placed therein may beperpendicular "under the punch-tbe table J is used, as before described.

uz, xox

In order, however, to ascertain exactly the required angle, we make useof the index-'plate M; and, to hold the table rigidly at the anglerequired, .we f'ur-` nish it with an arm, N, one endof' which is heldfirmly -upon the said table, and the other travels upon the said indexM.

This arm N is 'provided with some suitable mechanical device f'orfastening and holding it, when in the required position, upon the indexM.

l A table provided with a universal or ball-and-socket joint has longbeen in'use, and maybe equivalent to the table made use of by us; but ithas never before been arranged so as to .be rigidly held at the requiredangle while the operationv is beingperfbrmed.

The cams O P, which operate the fingers upon the bristles, and carry thesaid fingers and bristles forward and under the punch, are both placedupon the inain shaft, back of' the head O. This makes our machine muchmore compact, and, by the arrangements ,of the several parts which areoperated by the said cams, we are enabled to use them in' this positionto a' better advantage than when placed, as in the original'machine,upon an auxiliary shaft, besides making them more firm and sure in theiraction.

v The bristle-feed in our machine is of' silnilarconstruction to that inthe unachinc which is now used, but its position upon the machine, andits connection with the other improved parts, render its use entirelydifferent.

11n our improvement, the feed-belt is carried through the machine, andthe bristles are taken from the rear, and from the same side of' thehead O as the wire.

Placing the feed in this position, renders it more out of' the way, asit leaves the front of the machine, f'or the reception and working of'the block, upon the table J.

Q is a slide, placed upon the frame of the bristlefeed, and is operatedindirectly by means ot' the lever d and the cam O, but directly by theslide B.,as will hereafter be described.

Upon the under side of this slide, the fingers S S are held, in suchaway as to allow for their different movements.

Uponthe upper side of' the slide Q, and by means of which it isoperated,`,we place a smaller slide, It, which is connected directlywith the lever ci., and f'urp'ished with two angular slots, cut in itslower surace. 1

Into each of these slots, a pin or roller upon one of the fingers S S isfitted.

As the slide R advances, these slots act as a cam or incline uponA thepins, and force them apart, asv shown in figs. 3 and 5, and thusseparate the bristles.

\Vhen the said fingers have been thus forced apart to their properposition, the slide 1t comesin Contact with .the slide Q, which, withthe fingers thereto attached, is carried flu-ward the required distance,to allow the fingers to perform their function.

In the frame of' the slide Q, we place an inclined slot or cam, T.

Into this slot, a roller is fitted, which is held uponI the slide or piue, which extends horizontally from the said s'lotback ofthe slide R,upon which it operates.

When the slides Q and It are being carried forward,` the roller upon thepin e, which travels in the slot T, forces the said pin back ofthe slideR, and in Contact with. if, and thus prevents the slide from receding,nntil it is released by the drawing back of the pin e.

By thus preventing the slide R fi'om receding upon, the slide Q,as itwonld'were it not for the pin or slide e, we areable to keep the fingersS S locked or held apart for the first part of' `their backwardmovement, in order that they may not come in contact with the otherparts of the machine. I f is still. another-slide, which is operated bythe carni?.

in the vslide j, and extending partially into the projec-- tion g,asshown in fig..8.

When there is no difference in the thickness be- 'tween the two ends ofthe bunch, and the cam is not wanted,'it can be turned back, as' shownin black, iig. 8, s'o that it will not extend 4beyond the projection;but, in case it is wanted, it can be turned outward., as shown in red,figs. 8 and 9, and enlarge or widen the said projection.

Attached to and sliding upon the under side of the frame oi' thebristle-feed, just below the slide f, we --place a plate. or slide, A',which is operated, through the lever 7c, by the said slide jl Theobjectoi' this slide is to act upon the bristles immediatelyafter thefingers have relcased'them, and prevent any ofthe said bristles frombeing carried back with the fingers.

This completes'the construction of our improvements.

The operation is as follows:

After the machine has been set in motion, the bristles are brought`forward by the operation of the bristlefeed. A certain number,sutiicieut for one insertion, is passed forward. The divider H is nowreleased from the cam I, and immediately falls, and separates the bunchor tutt trom the mass'of bristles upon the feed. The fingers S S are nowforced apart, and

brought tbl-ward by the action of the slides Q and It and lever d, asbet'ore described, and the two ends of thel bunch or tuf't ot' bristlesare grasped between the said fingers and the projections g g, upon theslide f. 1f' one end of' the bunch exceeds the' other in thickness, thecam li is turned sufficiently to make up for this difference, and causeboth fingers to press equally hard upon the bristles. When the bristleshave been thus grasped, the tingers and slide f continue to advance,caused by the ,action ofthe cams Ol'and 11, until the bunch or tutt ispassed under the punch B, where it is held, until it is taken by thejaws'and punch, land inserted in the block.

When the tngersS S and slide Q advance, the slide R is forced forward tothe position shown in fig. 2. rlhe slide or pin e, attached tothe slideQ, advances with it.' 4

rlhe roller upon the said slide'or pin e travels in the slot i. As thesaid slides advance, this roller is brought in contact with the inclineofthe said slot T. This forces the pin e back ofthe slide R, as shown inblack, fig. 5. The roller no w travels in the ilu-ward part ot' theslot, which runs parallel with the slide Q.

NVhen the fingers have performed their work, and the slide begins torecede, the tendency would he to first draw the slide R back, and closethe fingers. This is prevented, by the position of' the slide or pin e,until the roller upon the said pin strikes and travels up the incline.This draws the pin e away from the slide R, as shown in red, iig. 5,which, when released, is immediately drawn back by the lever, andallowed to operate upon the fingers, and throw them together, as shownin red, iig..5. In this position, they are carried back, in readiness toagain operate upon the bristles.

As the slide f recedes, it operates the lever k, and

causes the plate or slide A to advance, as sh'own in red, figs. 6 and 7,which actsupon the bunch of brislies last set, and separates it from allconnection with the slide f and the fingers, and vprevents any bristlesfrom catching upon the same.

When the slide f advances, the plate A is immediately drawn back andaway from the punch, to allow the said punch to perform its work, and isthus held in readiness to operate agaiirimmediately after the i lengthof the stroke of this punch may be altered at anytime, by removing theblocks D and E, and inserting others in their places, provided withinclines, which have the suitable angle to give the 'requisite variationin the length of the stroke of' the punch.

The wire, after being carried into the machine by the wire-feed, andcut, is bent over the former by the descending of the jaws of the punch.After it has been thus bent, the said former F, by the action of thelever G, slides back and away from the wire, leaving the said wirebetween the jaws, by'which itl is carried downward over the bristles,and, bythe action of the punch, inserted in the block o1 brush-back.

The position of this block may be altered with reference to thepunch-that is, it may be placed nearer to or further from the saidpunchby raising or lowering the slide K, b'y means of the screw d.

When this slide isset at the proper distance from the punch, whichdistance must be governed by ythe thickness of the brush-back, the saidbrush-back, after it has been fastened upon the guide or pattern, isplacedl upon the table J of the machine. One of the holes in the guideor patterns is placed over the centre-pin L, which maybe raised orlowered, to suit convenience.

vThis brings the corresponding hole in the brush-block in the properposition for an insertion of bristles. 'It is thus held until thebristles have been set, and the punch withdrawn, when it is moved alonguntil the next hole is' brought over the centre-pin L,"whicl1 brings thenext hole in the brush-block in position.

When this is filled, it is moved on to the next, and

so on, until the whole brush is finished, or until all the holes in theblock have been filled. Bythis means, we are enabled to fill a block of'any length, and are not restrictechas in the original ma.- chine, to agiven sizeor shape of the block.
